Answer:
0.4 g/cm^3
Explanation:
The density of an object can be found using the following formula.
d= m/v
where m is the mass and v is the volume.
The mass of the metal is 6 grams and the volume is 15 centimeters^3
m=6 g
v= 15 cm^3
Substitute these into the formula.
d= 6 g/ 15 cm^3
Divide 6 g by 15 cm^3 (6/15=0.4)
d= 0.4 g/ cm^3
The density of the metal is 0.4 grams per cubic centimeter.
The acceleration of the jet is
Explanation:
Since the jet motion is a uniformly accelerated motion (=constant acceleration), we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the displacement
For the jet in this problem, we have
u = 0 (it starts from rest)
v = 40 m/s (final velocity)
s = 70 m (length of the runway)
Solving for a, we find the acceleration:

Once again, you'd need to know that there are 60 seconds in a minute, and 60 minutes in an hour :)
I'd say converting the minimum wage into cents rather than dollars would make this problem a lot easier. $8.25 = 825 ¢.
So if this person is earning 825 ¢ in an hour, we should divide 825 by 60 to find out how much they're making in a minute:
825 ÷ 60 = 13.75 ¢
Now, we just need to divide by 60 again to work out how much that is in seconds:
13.75 ÷ 60 = 0.229 ¢
So to answer your question, this person would make 0.229 ¢ a second (¢/s) on the job with minimum wage. Converting this value to dollars wouldn't be viable (as it'd just be $0.00, so it's best to leave the answer in cents!)
